Individuals with infertility exhibited significantly lower OBS compared to those with normal fertility (19.74 \u00b1 0.37 vs. 21.42 \u00b1 0.20). The OBS dietary and lifestyle components also had lower scores, with averages of 15.98 \u00b1 0.33 vs. 17.12 \u00b1 0.18 and 3.76 \u00b1 0.11 vs. 4.29 \u00b1 0.05, respectively. Weighted logistic regression results revealed that a one-point increase in OBS score was associated with a 3% decrease in infertility risk (Odds Ratio (OR) 0.97, 95% Confidence Interval (CI): 0.95, 0.99). Similarly, a one-point increase in OBS lifestyle score was linked to a 15% decrease in infertility risk (OR: 0.85, 95% CI: 0.75, 0.96), and a one-point increase in OBS dietary score was associated with a 2% decrease in infertility risk (OR: 0.98, 95% CI: 0.96, 0.99). Subgroup analyses revealed that individuals with no prior history of pregnancy benefited more from OBS and OBS lifestyle in terms of infertility risk reduction compared to those with a history of pregnancy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>OBS is found to have a negative correlation with infertility, particularly in cases of primary infertility.
